Don't forget the AC control head in the cab, and the high and low pressure switches on the AC system. There's also PAG oil, which is the lubricant in R134a based systems. Ester oil would be in the R12 systems. You'll also have heater hoses, which would be classified separately from the radiator hoses, and the water pump. Radiator fan and clutch also play a vital role in cooling system, as well as heater and AC.
